A Study on Device Security in IoT Convergence

IoT(Internet of Things) is global infrastructure that enables any object to communicate. The term IoT is being widely used and that technologies are being applied to various areas. IoT technologies is expected to increase many services' convenience, expandability, accessibility and interoperability, but existing ICT environment could be exposed new security threats due to increased openness and IoT device's specialty. Actually, IoT devices' vulnerabilities and exploits are reported. If attacks on IoT devices succeed, it can cause much damage over the various areas. Therefore, we categorize IoT devices and examines threats of each category. Finally we deduct security requirements of IoT devices.
